How Can I Format Strings with Variables in Python Using Format Strings?

Format Strings in Python

This question seeks a way to format a string in Python using a format string, allowing the inclusion of variables. Specifically, the goal is to achieve the following result:

String.Format("[{0}, {1}, {2}]", 1, 2, 3)

Answer:

Python supports string formatting using the format() method. The syntax is as follows:

string.format(arg1, arg2, ...)

where the arguments represent the values to be inserted into the string. The format specifiers in the string use numbers to indicate the position of the arguments.

To achieve the desired output, use the following code:

"[{}, {}, {}]".format(1, 2, 3)

This will produce the string [1, 2, 3].

Note:

For modern Python versions, it is recommended to use the newer f-strings for string formatting, as they provide a more concise and readable syntax. However, the above method is still valid for older versions of Python.
